I have a cold fusion plate kit, it says good up to a 250 shot. I want to run a 100 shot to begin my experience with nitrous. I'm going to do a walbro 255 in the tank. Im goi g to be mixing race fuel 50/50 until i get my tune set up for the nitrous. And I'm wondering what window switch I should get? Should I get a rpm switch and a window switch?
